RESUMEN

Purpose: Exploring the effects of acupuncture at the "Yizhi Tiaoshen" acupoint on blood oxygen metabolism and neurological function changes in the brain regions of AD model rats. Methods: The AD model was replicated by intraperitoneal injection of D-galactose combined with bilateral hippocampal CA1 injection of Okadaic acid (OA). Thirty rats with successfully replicated model were selected through Morris water maze experiment and randomly divided into model group, donepezil hydrochloride group, and acupuncture group, with 10 rats in each group. After treatment, fNIRs were used to detect changes in Oxy Hb, Deoxy Hb, and Total Hb in the cerebral cortex of rats in each group, in order to evaluate the neurological function changes in key brain areas. Results: The escape latency of the donepezil hydrochloride group and the acupuncture group was shortened, the number of crossings through the original platform increased, and the duration of stay in the quadrant where the original platform was located was prolonged. Based on fNIRs detection, the main differential channels of blood oxygen metabolism in AD rats were identified as 2-2 and 8-7, corresponding to the prefrontal and parietal lobes, respectively. The concentrations of Oxy Hb and Total Hb were significantly increased in both treatment groups, while the concentration of Deoxy Hb was significantly decreased. Conclusion: Acupuncture with the "Yizhi Tiaoshen" acupoint formula and donepezil hydrochloride can improve the learning and memory function of AD rats, and its mechanism may be related to improving blood oxygen metabolism in the prefrontal and parietal regions and protecting neuronal function.

RESUMEN

OBJECTIVE: This study investigated the clinical details and usage of Sa-am acupuncture in Korean medicine clinics and explored how practicing Korean medicine doctors (KMDs) think about Sa-am acupuncture. METHODS: We conducted a questionnaire-based survey of KMDs who utilize Sa-am acupuncture in their practice. The study comprehensively investigated issues related to clinical application of Sa-am acupuncture, needling techniques used during treatment, training methods, and directions for its future improvement. RESULTS: We analyzed 572 responses. An average of 50% of the patients visiting Korean medicine clinics were receiving Sa-am acupuncture. The most prevalent indication for Sa-am acupuncture use was digestive disorders. The patients' appetite level and digestive function were most frequently used indicators for selecting acupuncture points. Regarding prescription compositions, Jung-Gyuk formulas were more frequently used than Seung-Gyuk formulas. Inserting the needle along the flow of the channel or against the flow of the channel was most popular. The acupuncture style most frequently used in combination with Sa-am acupuncture was Ashi point acupuncture. Strengths of Sa-am acupuncture included its versatility, easy application, and good outcomes. Limitations included the lack of rigorous education and training programs, difficulty in applying the principles for beginners, and insufficient clinical research evidence. CONCLUSION: In clinics where Sa-am acupuncture is available, KMDs were providing Sa-am acupuncture to about half of their patients. Practitioners were not using all of the tonification and sedation techniques which may be due to time constraints or simply a lack of necessity. Sa-am acupuncture demonstrated high utility in clinical practice and high satisfaction based on the efficacy and safety. More training programs and high-quality research are needed to help expand the use of Sa-am acupuncture. Please cite this article as: Park JY, Lee YS, Park HJ, Lee SK, Lee JW, Kim SY.

RESUMEN

OBJECTIVE: To observe the effects of acupuncture at "antihypertensive acupoint prescription" on endothelial active factors and related autonomic neurotransmitters in spontaneous hypertension rats, and explore the vascular regulation and central regulation mechanisms of acupuncture for anti-hypertension. METHODS: Thirty SPF grade male spontaneous hypertension rats were randomly divided into a model group (15 rats) and an acupuncture group (15 rats). Besides, 15 Wistar Kyoto rats were collected as a blank control group (normal group). In the acupuncture group, acupuncture was delivered at the "antihypertensive acupoint prescription" (bilateral "Renying" [ST 9], "Quchi" [LI 11], "Zusanli" [ST 36], "Taichong" [LR 3] and "Neiguan" [PC 6]), with needles retained for 30 min, once daily. The duration of intervention was 28 days. Every week, using the the irritation scale, the sign of sympathetic irritation was evaluated dynamically. The arterial blood pressure of the rats tail was determined, using non-invasive blood pressure measurement system. ELISA was adopted to detect the levels of calcitonin gene-related peptide (CGRP), nitric oxide (NO), endothelin-1 (ET-1), neuropeptide Y (NPY) in the serum. DAB chromogenic in situ hybridization (CISH) was provided to detect the mRNA expression of endothelial nitric oxide synthase (eNOS) in the internal carotid artery and the arcuate nucleus (ARC), and that of CGRP in the paraventricular nucleus posterior (PVP) and the ventrolateral medulla (VLM). Liquid chromatography-mass spectrometry (LC-MS) was used to detect the levels of epinephrine (E) and norepinephrine (NE) in the paraventricular nucleus anterior (PVA). RESULTS: Compared with the normal group, the irritation scores, systolic blood pressure and diastolic blood pressure were increased at each time point in the model group (P<0.05). When compared with the model group, the irritation scores after the intervention for 3 and 4 weeks, and systolic and diastolic blood pressure after intervention for 2, 3 and 4 weeks were reduced in the acupuncture group (P<0.05). In comparison with the normal group, the serum CGRP and NO levels of the rats were decreased (P<0.05), and the serum ET-1 and NPY levels, as well as E and EN levels in PVA were increased (P<0.05) in the model group. The levels of serum CGRP and NO were elevated (P<0.05), and the serum ET-1 and NPY levels, as well as E and EN levels of PVA were reduced (P<0.05) in the acupuncture group when compared with those of the model group. In the model group, the media of internal carotid artery exhibited thickening and remodeling, while the neuron volume in ARC was small. In the acupuncture group, every layer of internal carotid artery was acceptably arranged, and the parvicellular neuron of ARC was moderate in volume. For the in situ hybridization of eNOS mRNA for the rats of each group, the smooth muscle cells were predominantly expressed in each layer of the internal carotid artery, whereas the expression of parvicellular neurons was dominated in ARC. In the model group, the large and small neurosecretory cells were distributed sparsely in the nerves of PVP; in the acupuncture group, the cells of these two species were distributed regularly; and there were few species of glial cell in the VLM of either the model group or the acupuncture group. In each group, for the in situ hybridization of CGRP mRNA, the small neurosecretory cells were expressed predominately in the PVP, while, the expression of glial cell nuclei and the cell cytoplasm was dominated in the VLM. Compared with the normal group, the mRNA expression of eNOS in the internal carotid artery and ARC and that of CGRP mRNA in the PVP and VLM was decreased in the model group (P<0.05). In the acupuncture group, when compared with the model group, the mRNA expression of eNOS in the internal carotid artery and ARC and that of CGRP in the PVP and VLM was increased in the acupuncture group (P<0.05). CONCLUSION: Acupuncture at "antihypertensive acupoint prescription" can upregulate the level of vascular relaxing factors, downregulate the level of contracting factors, enhance the response of relaxing factors in targeting blood vessels and regulating the center. The mechanism may be related to the modulation of the sympathetic-adrenergic autonomic neurotransmitters in the paraventricular nucleus in spontaneous hypertension rats.

RESUMEN

Background and aim: To evaluate the efficacy of three-point acupressure therapy in decreasing the dental anxiety in children undergoing dental procedures and to introduce acupressure as a simple, noninvasive, and cost-effective technique of reducing dental anxiety in children. Materials and methods: One hundred and sixty-eight, 8-12 years participants who met the inclusion criteria were randomly allotted to either group I (three-point acupressure) (n = 84) or group II (control) (n = 84). All children were subjected to a self-report measure of anxiety [Modified Child Dental Anxiety Scale (MCDAS)] 30 minutes before starting and after completing the dental treatment. For group I children, acupressure beads were applied on selected three acupoints for approximately 10 minutes and were left adhered in place. After 20 minutes, anxiety scores were recorded for all the children and allotted treatment procedure was initiated. For group II children, the same methodology was followed except for the application of acupressure beads. Frankl behavior (FB) rating scale, pulse rate (PR), and systemic saturation levels of oxygen were also recorded as secondary outcome measures. The data obtained was analyzed statistically using Chi-squared analysis, t-test, repeated measures analysis of variance (ANOVA) along with post hoc Bonferroni test. Significance level was predetermined at p ≤ 0.05. Results: At time frame (TF)-2, significant decrease in anxiety scores was observed in acupressure group irrespective of the treatment procedure, whereas in control group, it increased significantly. PR was also increased in acupressure group and FB scale was improved. In control group, PR increased and behavior was not improved. Between TF-2 and 3, no reduction in anxiety score was observed. Conclusion: The three-point acupressure therapy reduces anxiety in children undergoing dental procedures when compared to nonacupressure group and the difference was statistically significant. Acupressure is a noninvasive stimulation technique applied to acupoints and can be easily administered by a trained pediatric dentist. How to cite this article: Sisodia M, Kaur H, Garg N, et al.

RESUMEN

OBJECTIVE: To analyze the effects of Huoxue Qufeng Decoction combined with Tongguan Liquefying Acupoint Penetration therapy on swallowing function and quality of life in patients with ischemic stroke. METHODS: A total of 145 patients with post-stroke dysphagia admitted to Dingxi People's Hospital from January 2019 to May 2022 were selected with 65 patients in the control group and 80 patients in the observation group. The control group received Huoxue Qufeng Decoction alone, while the observation group received additional Tongguan Liquefying Acupoint Penetration therapy. Clinical efficacy, NIH Stroke Scale (NIHSS) score, Water Swallow Test, Swallowing Function Assessment (SSA) score, MD Anderson Dysphagia Inventory (MDADI) score, overall incidence of adverse events, and Swallowing Quality of Life (SWAL-QOL) score were compared between the two groups. RESULTS: The total response rate in the observation group was higher than that in the control group, with a statistically significant difference (P<0.01). After treatment, the SSA score and NIHSS score were statistically lower in the observation group than in the control group (P<0.01). The MDADI and SWAL-QOL scores were higher in the observation group than in the control group, with a statistically significant difference (both P<0.01). The total effective rate reflected by the Water Swallow Test was significantly higher in the observation group than in the control group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05). Univariate analysis revealed that age and treatment plan were factors influencing the recovery of swallowing function. Logistic multivariate regression analysis further identified age and treatment plan as independent risk factors affecting patient prognosis (P<0.05). CONCLUSION: Huoxue Qufeng Decoction combined with Tongguan Liquefying Acupoint Penetration has a significant effect on post-stroke dysphagia, effectively improving swallowing function and enhancing quality of life.

RESUMEN

Acupoint drug delivery is a traditional external therapy of traditional Chinese medicine(TCM). Guided by the meridian and collateral theory in TCM, it applies medications to the skin at acupoints, exerting a dual therapeutic effect by stimulating the acupoints and the conduction of meridians. Acupoint drug delivery is widely used in clinical practice. Different from traditional oral admi-nistration and injection, it absorbs medications through the skin, effectively avoiding the first-pass effect of drugs and the toxic side effects caused by injection. Acupoint selection and transdermal drug absorption are pivotal factors affecting the efficacy of acupoint drug delivery. Recent research on acupoint drug delivery mainly focuses on the evaluation of clinical efficacy, yet the systematic investigations on acupoint selection and pharmacodynamic factors are scarce. This study reviews the mechanism, efficacy evaluation and application status of acupoint drug delivery. It integrates the theory of TCM with modern medicine to explore the mechanism of acupoint drug delivery, evaluate its clinical efficacy, and assess the transdermal penetration in vivo and in vitro. The application status of acupoint drug delivery is also summarized, including the selection of acupoints, application dosage form, application time and the absorption of acupoints. This review aims to offer insights and references for the research, development and clinical application of acupoint drug delivery products.

RESUMEN

Recently, several previously undiscussed concerns in acupuncture research have been brought to light. Among these, the core issue stems from the ambiguity surrounding the identity of acupoints. Hence, the question "What is the identity of acupoints?" remains of particular importance in acupuncture research. To answer this question, we reviewed the original concept of acupoints explained in Oriental medicine, from which acupuncture treatment originated, and examined scientific research on acupuncture and acupoints. We then proposed a perspective on the identity of acupoints and speculated about a possible reason for their elusive nature: qi, which congregates at and flows in and out of acupoints, might be bioelectricity, making these points inherently difficult to measure anatomically or histologically. Consequently, acupoints are suggested to be spaces where bioelectricity congregates, thus inevitably exhibiting electrical characteristics.

RESUMEN

Temperature can reflect vital activities, and researchers have attempted to guide Chinese medicine diagnosis and treatment by observing acupoint temperature changes. Integrating a temperature sensor at the needle tip enables in situ acupoint temperature measurement. However, the sensor needles for acupoint temperature monitoring designed in previous studies were fabricated by manually soldering thermistor beads and metal wires, making mass production difficult. In this work, using MEMS manufacturing technology, a flexible temperature sensor that can be integrated at the needle tip is proposed and can be mass-produced on silicon wafers. The sensor uses a Pt thermistor as the temperature-sensing element and has a slender flexible structure with dimensions of 125 µm width by 3.2 cm length. As the sensor is inserted into a hollow needle, the Pt thermistor is glued to the needle tip. In the temperature range of 30 °C to 50 °C, the fabricated temperature sensor has a sensitivity of 5.00 Ω∙°C-1, a nonlinearity of ±0.39%FS, and a repeatability error of ±2.62%FS. Additionally, the sensor has been applied to in vivo acupoint temperature monitoring experiments in rats and demonstrated good performance, suggesting its promise for future research on acupoint temperature.

RESUMEN

BACKGROUND: Allergic rhinitis (AR) is a common inflammatory disease of the nasal mucosa that is characterized by symptoms such as sneezing, nasal congestion, nasal itching, and rhinorrhoea. In recent years, acupoint herbal patching (AHP) therapy has gained a growing interest as a potential management option for AR. This systematic review and meta-analysis will evaluate the clinical research evidence on the effectiveness and safety of AHP as a treatment option for AR outside of the Sanfu or Sanjiu days (summer or winter solstice). The results of this review will provide up-to-date evidence-based guidance for healthcare providers and individuals seeking alternative treatments for AR. METHODS: A comprehensive search of electronic databases (PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, China National Knowledge Infrastructure (CNKI), CQVIP, Sino-Med, and Wanfang Databases) will be conducted from their inception to June 2023. The inclusion criteria will be limited to randomized controlled trials that evaluate the effectiveness or efficacy of non-Sanfu or non-Sanjiu AHP for AR. The primary outcome measure will be the total nasal symptom score. The methodological quality of included studies will be assessed using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2), and meta-analyses will be performed using RevMan (V.5.3) statistical software. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach will be used to determine the certainty of evidence. DISCUSSION: This systematic review and meta-analysis will provide valuable insights into the effectiveness and safety of non-Sanfu or non-Sanjiu AHP as a treatment option for AR. The study aims to produce a high-quality review by adhering to PRISMA-P guidelines and using clinical guideline recommended outcome measures. The results of this review may offer additional treatment options for AR patients who seek complementary and alternative therapies, and hold significant implications for future research in this field. Overall, this study has the potential to inform clinical practice and improve patient outcomes. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42022181322.

RESUMEN

BACKGROUND: Chronic spontaneous urticaria (CSU) is a common chronic inflammatory skin disease that manifests as itching and wheals, seriously affecting quality of life. Clinical observations and previous research trials have shown that acupuncture is safe and effective for the treatment of CSU. However, there are problems, such as a short duration of action and frequent treatment. Compared with traditional acupuncture, acupoint catgut embedding (ACE) has the advantages of a longer effect and higher compliance. Clinical trials are needed to prove its efficacy and mechanism of action. OBJECTIVE: This trial aims to provide definitive evidence for the treatment of CSU with ACE and explore the mechanism of ACE. METHODS: This is a randomized, double-blind, placebo-controlled trial. In this trial, 108 participants aged 18-60 years with a diagnosis of CSU and no history of ACE will be randomly assigned to 2 groups (1:1 ratio) using the Statistical Analysis System: treatment (ACE) and control (sham ACE). The participants and efficacy evaluators will be blinded to the grouping. Both the ACE and sham ACE groups will undergo acupuncture, but the sham ACE group will not receive catgut sutures. Treatment will be performed twice weekly for 8 weeks, with a 1-week run-in period and a 16-week follow-up period. Twenty patients will be randomly selected to undergo functional magnetic resonance imaging before and after the treatment period. The primary outcome will be the urticaria activity score over 7 days (UAS7). We will use R (version 4.0.1; R Project for Statistical Computing) to perform ANOVA and independent samples t tests to compare the differences within and between groups before and after treatment by judging the rejection range based on a significance level of .05. RESULTS: The study protocol has been approved by the Ethics Committee of Guang'anmen Hospital on September 7, 2022, and has been registered on November 30, 2022. Recruitment began on March 1, 2023. A total of 4-6 participants are expected to be recruited each month. The recruitment is planned to be completed on March 1, 2025, and we expect to publish our results by the winter of 2025. As of November 1, 2023, we have enrolled 25 participants with CSU. CONCLUSIONS: This randomized, double-blind, placebo-controlled trial aims to provide definitive evidence for the treatment of CSU with ACE and explore the mechanism of ACE. We hypothesize that wheals and itching will show greater improvement in participants receiving active therapy than in those receiving sham treatment. The limitations of this study include its single-center trial design, small sample size, and short treatment duration, which may have certain impacts on the research results.

RESUMEN

OBJECTIVE: To evaluate clinical effect and safety on the basis of detecting the specific response of jing-well point in treatment of intractable insomnia with acupuncture by meridian differentiation. METHODS: Sixty-four patients with intractable insomnia were randomized into an observation group (32 cases, 1 case dropped out and 1 case was eliminated) and a control group (32 cases, 1 case was eliminated). In the observation group, the meridian imbalance value detected at the jing-well point was taken as the evidence so that the corresponding yuan-source and back-shu points were stimulated with acupuncture. In the control group, the routine acupuncture was operated at Baihui (GV 20), Sishencong (EX-HN 1), and bilateral Shenmen (HT 7), Sanyinjiao (SP 6), Shenmai (BL 62) and Zhaohai (KI 6). Besides, the detection at jing-well point was performed for blindness in the control group. In the two groups, the interventions were delivered once daily, 5 times a weeks and for consecutive 4 weeks. In the two groups, the scores of Pittsburgh sleep quality index (PSQI), insomnia severity index (ISI) and the TCM symptom scale were observed before treatment and after 2 and 4 weeks of treatment; the clinical effect and safety were evaluated after treatment; the changes of meridian imbalance value were observed before and after treatment and the correlation analysis with the total score of PSQI was conducted. RESULTS: After 2 and 4 weeks of treatment, except the scores for hypnotic drug in the two groups and sleep disorder after 2 weeks of treatment in the control group, the scores of the other factors and the total scores of PSQI were all reduced when compared with those before treatment in the two groups (P<0.05). After 4 weeks of treatment, except the scores for hypnotic drug in the two groups and sleep disorder in the control group, the scores of the other factors and the total scores of PSQI were lower than those after 2 weeks of treatment in the two groups (P<0.05). After 2 weeks of treatment, the scores for time to fall asleep, sleep efficiency and daytime dysfunction in the observation group were lower than those of the control group (P<0.05); and after 4 weeks of treatment, except the scores for sleep disorder and hypnotic drug, the scores of the other factors and the total score of PSQI in the observation group were all lower than those of the control group (P<0.05). After 2 and 4 weeks of treatment, ISI scores and the scores of TCM symptom scale decreased when compared with those before treatment (P<0.05), and the scores of these two scales after 4 weeks of treatment were lower than those after 2 weeks of treatment (P<0.05) in the two groups; and the scores in the observation group were lower than thoese in the control group (P<0.05). The total effective rate was 93.3% (28/30) in the observation group, higher than that (90.3% [28/31]) in the control group (P<0.05). Of 64 cases, there was only 1 case of mild hematoma in the control group; and no any other adverse events occurred. Among 64 cases, the meridians, with the imbalance frequency ≥30 times, included the pericardium meridian of hand-jueyin and the heart meridian of hand-shaoyin; those with the imbalance frequency ≥20 times, were the kidney meridian of foot-shaoyin, the triple energizers meridian of hand-shaoyang, the gallbladder meridian of foot-shaoyang, the spleen meridian of foot-taiyin and the stomach meridian of foot-yangming. Except the lung meridian of hand-taiyin in the control group, the imbalance value of each meridian was reduced after treatment (P<0.05, P<0.001, P<0.01), and the meridian imbalance value presented a linear positive correlation with the total score of PSQI in the two groups . CONCLUSION: Meridian differentiation acupuncture based on detecting the specific response of jing-well point can significantly improve the sleep quality and reduce the related symptoms in the patients with intractable insomnia. This therapy promotes the conversion of the meridians from the imbalance to the balance and is satisfactory in its safe operation.

RESUMEN

OBJECTIVE: To observe the clinical efficacy of acupoint massage, acupoint sticking combined with moxibustion at Shuidao (ST 28) for postpartum urinary retention. METHODS: A total of 120 patients with postpartum urinary retention were randomly divided a triple-combination group, a double-combination group, and a massage group, with 40 patients in each group. All groups received standard postpartum care to stimulate urination. The patients in the massage group received rapid acupoint massage at the bilateral Shuidao (ST 28); the patients in the double-combination group additionally received acupoint sticking of self-made Tongquan powder at bilateral Shuidao (ST 28); the patients in the triple-combination group further received moxibustion at bilateral Shuidao (ST 28). The treatment was given once in all three groups. After 5 hours of treatment completion, bladder residual volume was measured; the time and volume of first urination as well as total urination volume after 5 hours of treatment completion were recorded; the patients' sensation of urination smoothness, satisfaction rate, length of hospital stay, and hospital costs were evaluated. RESULTS: The triple-combination group showed significantly lower residual urine volumes (P<0.05), earlier first urination time (P<0.05, P<0.001), and higher first urination volumes and total urination volumes after 5 hours of treatment completion compared to the other two groups (P<0.05, P<0.001). The sensation of urination smoothness and patient satisfaction were also significantly better in the triple-combination group (P<0.001, P<0.05). The double-combination group had higher volume of first urination and total urination volume after 5 hours of treatment completion than the massage group (P<0.05), and better sensation of urination smoothness and patient satisfaction (P<0.05). There was no significant difference in the length of hospital stay and costs among the three groups (P>0.05). The total effective rates were 100.0% (40/40) for the triple-combination group, 90.0% (36/40) for the double-combination group, and 70.0% (28/40) for the massage group, with the triple-combination group significantly outperforming the other two groups (P<0.05, P<0.001), and double-combination group outperforming the massage group (P<0.05). CONCLUSION: Acupoint massage, acupoint sticking combined with moxibustion at Shuidao (ST 28) could effectively improve urination in patients with postpartum urinary retention, and enhance patient satisfaction.

RESUMEN

OBJECTIVES: To analyze the rules of acupoint selection in treatment of cancer-related insomnia with acupuncture and moxibustion by data mining technology. METHODS: The articles of cancer-related insomnia treated with acupuncture and moxibustion were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, WOS, Cochrane, and Embase databases, from the inception of each database to January 5, 2024. The prescription database of acupuncture and moxibustion for cancer-related insomnia was established. The descriptive analysis was conducted on the use frequency, meridian tropism and distribution of acupoints. Using SPSS Modeler 18.0 Apriori algorithm, the association rules of acupoint prescriptions were analyzed. With Cytoscape3.9.1 software used, the complex network diagram was plotted, and the cluster analysis of high-frequency acupoints was performed by SPSS26.0 software. RESULTS: Forty-one articles were included, and 67 prescriptions were extracted with 89 acupoints involved, and the total use frequency was 447 times. The top 4 acupoints of the high use frequency were Baihui (GV20), Sanyinjiao (SP6), Shenmen (HT7) and Shenting (GV24). The included meridians were the governor vessel, the spleen meridian, the bladder meridian, the conception vessel, the heart meridian and the stomach meridian. The selected acupoints were mostly distributed on the head, the neck and and the upper and lower limbs. The special acupoints of the high use frequency included the five-Shu points, the crossing points and yuan-primordial points. Regarding acupoint combination, GV24, SP6, HT7, and GV20 were highly correlated. The three effective clusters were categorized among the top 12 acupoints of the high use frequency. CONCLUSIONS: In treatment of cancer-related insomnia with acupuncture and moxibustion, the principle focuses on supporting the healthy qi, eliminating pathogens, regulating yin and yang, promoting the circulation of the governor vessel for regulating the spirit, and tranquilizing the mind. The core acupoint prescription may includes GV24, SP6, HT7 and GV20；combined with Zusanli (ST36) and Yintang (GV4+) to enhance the therapeutic effect.

RESUMEN

Based on Huangdi Neijing (Yellow Emperor's Internal Classic), combined with the Huangdi Mingtang Jing JiJiao (Compilation and Correction of Yellow Emperor's Mingtang Classic) and unearthed Tianhui Yijian (Tianhui Medical Bamboo Slips), it is recognized that the therapeutic indications of Fenglong (ST 40) were recorded repeatedly in many medical works of the Qin and Han dynasties; and the treatments mostly focus on "upward reversion of qi ". In Huangdi Mingtang Jing (Yellow Emperor's Mingtang Classic), a part of symptoms were re-described textually, which affects the understanding on the indications of Fenglong (ST 40) in the medical works of the later generations. On the basis of the construction of phlegm theory in the Sui and Tang dynasties, the scholars of Song, Jin and Yuan dynasties had placed the emphasis on the relationship between phlegm and qi movement. In acupuncture works by Dou Hanqing, Fenglong (ST 40) was selected in treatment of phlegm dampness and phlegm-induced asthma, which is also based on the pathogenesis, "upward reversion of qi ", rather than "phlegm" itself. This view can be understood by the proof of "reducing Zusanli (ST 36) for eliminating wind". The relationship between Fenglong (ST 40) and phlegm was emphasized in Yulong Ge (Jade Dragon Verse) and Zhenfang Liuji (Six Sets of Acupuncture Methods), after which, the understanding, " Fenglong (ST 40), the key point for phlegm disorders", had been formed gradually since the Ming dynasty. The formation and evolution of the therapeutic indications of Fenglong (ST 40) are influenced comprehensively by the errors in textual duplication, cultural background, changes in the term expressions of disorders, and the clinical experience of medical practitioners.

RESUMEN

BACKGROUND: High doses of long-acting opioids were used to facilitate off-pump coronary artery bypass grafting procedure, which may result in opioid-related adverse events after surgery. Transcutaneous electrical acupoint stimulation (TEAS) had been reported to be effective in reducing intraoperative opioids consumption during surgery. The aim of this study is to assess whether TEAS with difference acupoints can reduce the doses of opioid analgesics. METHODS: This was a multicenter, randomized, controlled, double-blind trial. Patients underwent off-pump coronary artery bypass grafting under general anesthesia were enrolled. Eligible patients were randomly and equally grouped into sham acupuncture group (n = 105), regional acupoints combination group (n = 105), or distal-proximal acupoints combination group (n = 105) using a centralized computer-generated randomization system. Transcutaneous electrical acupoint stimulation was applied for 30 min before anesthesia induction. The primary outcome was the doses of sufentanil during anesthesia. Secondary outcomes included the highest postoperative vasoactive-inotropic scores within 24 h, intraoperative propofol consumption, length of mechanical ventilation, duration of cardiac care unit and postoperative hospital stay, incidence of postoperative complications, and mortality within 30 days after surgery. RESULTS: Of the 315 randomized patients, 313 completed the trial. In the modified intention-to-treat analysis, the doses of sufentanil were 303.9 (10.8) µg in the distal-proximal acupoints group, significantly lower than the sham group, and the mean difference was - 34.9 (- 64.9 to - 4.9) µg, p = 0.023. The consumption of sufentanil was lower in distal-proximal group than regional group (303.9 vs. 339.5), and mean difference was - 35.5 (- 65.6 to - 5.5) µg, p = 0.020. The distal-proximal group showed 10% reduction in opioids consumption comparing to both regional and sham groups. Secondary outcomes were comparable among three groups. CONCLUSION: Transcutaneous electrical acupoint stimulation with distal-proximal acupoints combination, compared to regional acupoints combination and sham acupuncture, significantly reduced sufentanil consumption in patients who underwent off-pump coronary artery bypass grafting surgery.

RESUMEN

BACKGROUND: A history of severe nausea and vomiting during pregnancy (SNVP) is a risk factor for postoperative nausea and vomiting (PONV). This study aimed to explore potentially effective treatment strategies and potential genetic factors underlying SNVP risk-related PONV. METHODS: A total of 140 female patients undergoing breast cancer surgery were assigned to either the study group (70 with SNVP) or the control group (70 with mild to moderate nausea and vomiting during pregnancy (MNVP)). Patients in each group were randomly assigned to two different treatment subgroups and received either ondansetron plus dexamethasone (OD) or OD + TEAS (ODT) (transcutaneous electrical acupoint stimulation, TEAS). Blood samples were collected from patients before induction (D0) and 24 h (D1) after surgery for growth differentiation factor 15 (GDF-15) evaluation. The primary outcome was the incidence of PONV within 36 h. The secondary outcome was the serum GDF-15 level. RESULTS: The incidence of PONV in the SNVP group was significantly higher than that in the MNVP group within 24 h (P < 0.005). In the SNVP group, ODT-treated patients had less PONV than those in the OD-treated group during the 6-12 h (P = 0.033) and 12-24 h (P = 0.008) intervals, while within 6 h, there were fewer vomiting cases in the ODT-treated group (SNVP-ODT vs. SNVP-OD, 7/33 vs. 19/35, P = 0.005). The preoperative GDF-15 serum levels in patients with SNVP were significantly higher (P = 0.004). Moreover, higher preoperative GDF-15 serum levels correlated with a higher incidence of PONV (P = 0.043). CONCLUSIONS: TEAS showed significant effect on PONV treatment in patients with SNVP. A higher serum GDF-15 level was associated with a history of SNVP, as well as a higher risk of PONV.

RESUMEN

Chronic cerebral ischemia (CCI) is a common neurological disorder, characterized by progressive cognitive impairment. Acupoint catgut embedding (ACE) represents a modern acupuncture form that has shown neuroprotective effects; nevertheless, its effects on CCI and the mechanisms remain largely unknown. Here, we aimed to explore the therapeutic action of ACE in CCI-induced cognitive impairment and its mechanisms. The cognitive function of CCI rats was determined using Morris water maze test, and histopathological changes in the brain were assessed through hematoxylin-eosin (HE) staining. To further explore the molecular mechanisms, the expression levels of oxidative stress markers and the Ang II/AT1R/NOX axis-associated molecules in the hippocampus were evaluated using enzyme-linked immunosorbent assay (ELISA), western blotting, and immunohistochemistry. Here, we observed that ACE treatment alleviated cognitive dysfunction and histopathological injury in CCI rats. Intriguingly, candesartan (an AT1R blocker) enhanced the beneficial effects of ACE on ameliorating cognitive impairment in CCI rats. Mechanistically, ACE treatment blocked the Ang II/AT1R/NOX pathway and subsequently suppressed oxidative stress, thus mitigating cognitive impairment in CCI. Our findings first reveal that ACE treatment could suppress cognitive impairment in CCI, which might be partly due to the suppression of Ang II/AT1R/NOX axis.

RESUMEN

Acupoint-stimulating therapies have often been used to manage stroke-related spasticity and motor dysfunction. However, the effects of different acupoint-stimulating therapies in older stroke survivors have been unclear. This systematic review and network meta-analysis compared the effects of different acupoint-stimulating therapies in managing spasticity and motor dysfunction in older stroke survivors. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched 7 databases for studies published up to July 2023. Inclusion criteria were: (1) older adults with strokes; (2) treatments were acupoint-stimulating therapies; (3) a control group did not receive acupoint-stimulating therapy, or the study compared different acupoint-stimulating therapies; and (4) outcomes included spasticity and motor function. Methodological quality was assessed with Risk-of-bias tool for randomized trials version 2, while R and Metainsight were used to conduct the network meta-analysis. We analyzed 27 studies and the results showed that non-invasive electroacupuncture and warm acupuncture were more effective in reducing spasticity than conventional acupuncture (standardized mean difference and 95 % confidence intervals = 1.35/1.19 [0.57; 2.13/0.54; 1.83]) and invasive electroacupuncture (standardized mean difference and 95 % confidence intervals = 0.96/0.80 [0.12; 1.80/0.08; 1.51]). Conventional acupuncture and invasive electroacupuncture were effective in improving motor function (standardized mean difference and 95 % confidence intervals = 0.99/1.41 [0.42; 1.56/0.54; 2.28]). However, there was significant inconsistency for the effects of invasive electroacupuncture between studies. Our findings suggest that for older stroke survivors with spasticity, non-invasive electroacupuncture and warm acupuncture are appropriate, whereas conventional acupuncture is more appropriate for patients aiming for motor recovery. SYSTEMATIC REVIEW REGISTRATION: This study was registered in the PROSPERO database (CRD42023442202).
